Clean drinking water is arguably the most basic human necessity, yet in developing countries it’s a rare and precious resource — nearly 900 million people worldwide live without it, according to the World Health Organization. One MIT researcher has a solution: Drink the fog.
A new flexible mesh can envelop airplanes, cars and other devices in a spidery cloak of sensors, designed to act as a network of nerves warning a machine of stress and damage.
Taking a cue from super-thin, super-strong spiderwebs, Stanford researchers designed a matrix of sensors that can wrap around an aircraft or other piece of machinery. The sensors can connect to a computer, warning a pilot or driver about any cracks or strains in the machine before they cause serious damage or injury.
Implanting clunky electrodes or other devices inside people's heads could someday give way to smoother, silkier neuromedicine. Scientists say that they have successfully measured the electrical activity of cat brains by using a silk-silicon surface mesh, according to Technology Review.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
